South African safari ranger Naas Smit said: ”Only those who work in the wild know the speed of a lion and it could have torn the arm off the person touching it. “It would have the power to pull that tourist straight out of that window and kill them instantly in front of their friends. It was an incredibly stupid thing to do. “It could also just have easily crashed its way through the open window and torn into those inside. They were lucky to get away with it. They are wild animals.“If the lion had killed this person then game rangers would probably have had to have killed it and if it was the pride male it could have serious consequences.
